SCSI Hard Drives
The system supports Adaptec Ultra 160/m SCSI SCA type or slower hard drives that are 3.5 inches
wide. Contact a sales representative or dealer for a list of approved SCSI devices.
Mounting a SCSI Hard Drive in a Carrier
1. Remove the 3.5-inch wide hard drive from its wrapper and place it on an antistatic surface.
2. Record the drive model and serial number in your equipment log (page 91).
3. Remove the carrier filler panel and save the screws. You need them later in this procedure.
4. Orient the drive so the connector is near the top and rear of the drive carrier. Figure 8 shows
the orientation of the drive in the carrier. The carrier is upside down in this figure.
5. Using the screws from step 3 or other screws of the correct size and length (not supplied),
attach the carrier to the drive.
Removing a SCSI Hard Drive
A bank of five LEDs on the front of the hard drive bays monitors the drive status of each drive in
the hot-docking bay. Each LED corresponds directly to a drive, so that the upper-most LED shows
activity in the upper-most drive. The LEDs and corresponding drives are numbered (left to right)
zero to four. When a yellow LED for a hard drive is on continuously, you are permitted to
hot-swap (replace) a bad drive with a good one. If the operating system installed supports
hot-swapping hard drives, the system DOES NOT need to be powered off.
